We're dividing 163149 by 72 
We're looking to find how many times 72 goes into 163149.

Let's proceed to step 1:
If we divide 1 by 72, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 72

Step 2:
When dividing 16 by 72, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 72

Let's proceed to step 3:
72 goes into 163 2 times with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 144 from 163 to get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 72

Moving on to step 4:
72 goes into 191 2 times with a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 144 from 191 and we're left with 47.
Grab the next digit (4) from the dividend, add it to 47, then carry on: 474 / 72

Moving on to step 5:
474 divided by 72 is 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Deduct 432 from 474 and we're left with 42.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 72

Going ahead to step 6:
The number 72 fits into 429 5 times, leaving a remainder of 69.
Put 5 as the next digit of the answer. 
Result so far: 2265.0
Deduct 360 from 429 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
690 divided by 72 is 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 2265.9
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
The number 72 fits into 420 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 2265.95
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2265.958
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 72, we get 3 and a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 2265.9583
If we subtract 216 from 240, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
72 goes into 240 3 times with a remainder of 24.
The next digit of our result is 3. 
Result so far: 2265.95833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 2265.95833, with a leftover of 2.4e-05.
